Abstract
The invention relates to a cooking agent for papermaking and pulping and a preparation method thereof. The cooking agent for papermaking and pulping comprises the following components in weight percentage: 25-35wt% of alkyl sodium sulfonate, 4-10wt% of anthraquinone sodium sulfonate, 8-16wt% of fatty alcohol-polyoxyethylene ether, 2-4wt% of an anti-settling thixotropic agent-bentonite, 0.5-1wt% of a flatting agent, 0.5-1wt% of an antifoaming agent, and water. The preparation method comprises the following steps: (1) heating the water to 50-60 DEG C; (2) adding the anthraquinone sodium sulfonate to be grinded for 50-70 minutes; (3) adding the alkyl sodium sulfonate and the fatty alcohol-polyoxyethylene ether (2 to 10 ether), heating to 60 DEG C, adding 2-4wt% of the anti-settling thixotropic agent-bentonite, 0.5-1wt% of the flatting agent and 0.5-1wt% of the antifoaming agent and stirring for 30 minutes to obtain the product. The cooking agent for papermaking and pulping has the advantages of enhancing the pulping yield by 1 to 4%, strengthening the fiber strength, reducing the bleaching loss by 2 to 3%, shortening the cooking time; being more beneficial to alkali recovery and increasing the yield of the recovered alkali, and reducing environmental pollution; and the cooking agent is more suitable for a continuous cooking technology and a DDS technology for the most advanced equipment in the papermaking industry.
Description
Technical field
The present invention relates to auxiliary agent and the manufacture method thereof used in a kind of paper industry, especially relate to a kind of chemicals used in pulping digestion and manufacture method thereof.
Background technology
At present, domestic papermaking enterprise is used for the auxiliary agent of pulping by cooking, mostly is akali sulphide, and environmental pollution is comparatively serious.
Chinese patent ZL discloses for No. 02139858.5 and has a kind ofly added the formulated digesting assistant of water by materials such as bleeding agent BS, niter cake, sodium chloride, peregal, fatty alcohol-polyoxyethylene ether, sodium alkyl sulfonates, has solved to a certain extent problem of environmental pollution.But remain in following shortcoming: (1) bleaching loss is higher;
(2) mobile not good enough, be unfavorable for that alkali reclaims; Have the pipeline scale problem, the chemical recovery system maintenance cycle is shorter.
Summary of the invention
The object of the invention is to overcome the defects that existing digestant exists, provide a kind of one-tenth pulp yield high, float to decrease to hang down also and can improve fibre strength, and environmental pollution is few, be conducive to alkali and reclaim, and be convenient to adopt chemicals used in pulping digestion and the manufacture method thereof of continuous steaming-boiling technology use
Technical scheme of the present invention is:
The present invention's chemicals used in pulping digestion is formulated by following raw material and weight percent proportioning: the preferred 6-8% of sodium anthraquinone sulfonate 4-10%(), the preferred 27-32% of sodium alkyl sulfonate 25-35%(), the preferred 10-12% of fatty alcohol-polyoxyethylene ether (2-10 ether) 8-16%(), the preferred 2-3% of anti-settling thixotropic agent bentonite 1-4%(), levelling agent 0.5-1%, defoamer 0.5-1%, Yu Weishui.
The present invention's chemicals used in pulping digestion manufacture method may further comprise the steps: (1) takes by weighing each raw material components by the predetermined weight proportioning; (2) water is heated to 50～60 ℃; (3) add anthraquinone sulfonic acid and receive, ground 50-70 minute, (4) adding alkyl sulfonic acid is received and fatty alcohol-polyoxyethylene ether (2-10 ether), is heated to 60 ℃, and (5) add anti-settling thixotropic agent bentonite, levelling agent and defoamer again.
Product of the present invention can be high temperature resistant for a long time, and anti-highly basic can reduce fiber and half fiber generation peeling reaction and basic hydrolysis at final stage of cooking, thereby can protect fibre strength and improve into pulp yield.
Product of the present invention has high molecular complexing function, with the chromophoric group in the various fibrous raw materials and complexing of metal ion shielding, reduce the redox of degradation product, prevent chromophoric group and lignin generation condensation reaction, improve the mashing off presentation quality, reduce the slurry appearance luster, be conducive to rinsing and improve whiteness.
Product of the present invention has good emulsification and diffusion, and the colloid that broken away from, lignin, resin etc. are evenly spread in the black liquor, is not adsorbed once again by fiber.
In a word, compare with Chinese patent 02139858.5 disclosed papermaking pulping cooking auxiliary, use the present invention's chemicals used in pulping digestion, can save the boiling cost, save amount of caustic soda, shorten digestion time, energy savings; Improve into pulp yield 1-2wt%; But fortifying fibre intensity improves pulp quality; Reduce to float and decrease 2-3%; Substantially stop sulphide staining, reduce the contaminated wastewater load, reduce the harmful substance in the waste water, COD content obviously reduces; Alleviate equipment and pipeline corrosion and fouling, save maintenance cost; The black liquor good fluidity, less scaling, be of value to the good operation of chemical recovery system; Simultaneously, to different fibrous raw materials, different pulping process, different digesting apparatus has good adaptability; Because the distinctive dissolubility of this product, permeability, dispersive property, state-of-the-art continuous steaming-boiling technology and DDS digesting technoloy more have unique adaptability advantage in the world at present to paper industry.
Product of the present invention uses safety, convenient, and it is also extremely convenient to store, transport.
